The Spyder Men's Powergrade Dry W.e.b. T-neck is a great shirt for chilly days, and it’s perfect for layering. The fabric is constructed with the DRYWEB technology that employs a multi-layer structure that absorbs perspiration quickly then rapidly transports it to the outer layer of the fabric using a natural process called capillary action. Spun polyester on the inside pulls moisture away from the skin, and micro-fiber filament polyester on the surface disperses moisture for quick evaporation. Treated with an anti microbial, non pill finish, this fabric resist odor causing bacteria. It is cut with a regular fit. A zippered collar with a web print design on the gusset adds style to this comfortable long sleeve shirt.
